Make sure you installed VARA-HF modem. It can be downloaded from HERE
Unpack (Unzip) VarAC in a dedicated directory. c:\VarAC can be a good place. DO NOT run it directly from the zip file!
Launch VarAC by double clicking the VarAC.exe file.
You will be asked to enter your callsign in the "My callsign" text box.
On the top menu select: Settings --> RIG control & VARA Configuration
Set your desired PTT and Frequency control modes (CAT/OmniRig/RTS/DTR) and use the TEST buttons to make sure they work. You can find here some screenshots of popular rigs configurations made by VarAC community members.
To allow VarAC to automatically launch your VARA modem, tell VarAC where the VaraHF modem is located under the "VARAHF main file path" section. Point it out to the VARAHF.EXE file you installed on step #1 (or VARAFM.EXE if you use VaraFM)
Make sure you select the right VaraHF port in the "VARAHF main port" section. The default port of VaraHF modem is 8300
VarAC allows you to send anychroneous messages - also known by the name broadcast. A broadcast is a AX25 message (similar to APRS). You can send to one person or to all. Unlike a VarAC QSO, there is no delivery-guaranteed mechanism in broadcasts.
A friendly tip
You can use broadcasts for group chat when you and your partners have good signals
The QSY code of behavior
The calling frequencies are used for finding QSO mates and for short QSOs only.
If you are enjoying your QSO and want to continue chatting with your partner, then after ~5 minutes, invite your partner to QSY. You don't need to disconnect. QSY happens while you are connected
How? This is done by clicking the QSYU/QSYD buttons that will take you +/- 750Hz
This will initiate a QSY request that will instruct both sides to change frequency while chatting.
If set your CAT frequency control under the VarAC settings menu, then VarAC will QSY for you automatically.
Again: No need to disconnect prior or during to the QSY.
Still have questions ?
This quick start guide include the must have things you need to know. But VarAC has so many other features you can explore such as File transfer, Frequency scheduler, PSKreporter integration, Last heard peeking etc.
